Abstract

The bonding material used to make the grinding wheel determines the strength of the grinding wheel during the grinding process. Poor bonding is a significant problem in the grinding process, affecting work piece interaction, grinding force, surface finish, and wheel performance. To improve the bonding strength of the grinding wheel, Al2O3 with Boron Nitride vitrified bonded grinding wheel samples were investigated in this study. The bonding strength properties of Al2O3 grinding wheels with 10%, 15%, and 20% Boron nitride were compared to those of Al2O3 + 0% Boron nitride grinding wheels. The compression and shear strength of the grinding wheel were tested under various conditions by keeping the grinding wheel in lateral and axial positions against the applied load. The maximum compression strength values were 125.7 MPa and 19.8 MPa for axial and lateral position, and the maximum shear strength values were 42 MPa compared to the wheel made out of Al2O3 alone.
